How often do you engage your 4WD?

Don't go off-road much with my 4-Runner, but try to engage the 4WD on a regular basis, just to keep it reliable. Would be interested to know how often other members cycle their 4WD drive, especially on vehicles that don't go off-road much.

But ive had more issues with Locker not working over time then the 4WD not working. On my 1st Gen Tacoma when I first purchased it had locker problems had to take if off and test bench cycle it and replace the grease. The girl I bought it from NEVER used it. But as for my 4runner ive never had issues EVER. Probably cause I'm often on a trail. Works super easy to use when you do the Anytime locker mod.

2-3x a month lately. Don't actually need it 90% of the time, but whenever I hit dirt I throw it into 4hi. I really need to cycle the center diff and 4low more often, but Carmax paid for a brand new actuator before I took possession so it's not sticky at the moment.
